The issue is not the dynamic range, the main issue are reflections, and that's why the polarizer works to make the picture better, because polarizers block a specific light rays that come from a specific direction.
Correct. 👍
At 7:22, he removed the ring light and suddenly, you can read the capacitors using just the indirect light.
@@bblod4896 Silly part about it is that he showed that he can lower the power of the ringlights at the beginning of the video, then didn't use that feature again, which would have allowed him to see whichever part he wished to - obviously is a bit more messing around to change intensity to view different things. I just use a bright led torch held at an angle if I wish to see something that's proving difficult...
@@bblod4896 Exactly !. I think the point is (as made by someone else here) use a separate light and point it yourself to see something that is proving difficult to see. It is the adjustability of the polariser which is key but you get the same effect with a separate tiny hand held light which you move to where it gives the best results. The polariser is more convenient though and if you are working with two hands it's easier. There is often a solution to a problem - when you spend money that is.
Hmmm?? WDR or Wide Dynamic Range is the anti reflection or clearing reflection. I'm using the right microscope with WDR and I have no problem's with reflection, I can pull up the light on 100 %. and clearly read all information from ics .... And u have to pull down u light to read something? And telling him the issue is the reflection 😂😂 He is 100 % right.
The best picture for me was actually when you were changing lights, so when there was no ring mounted :)
it would be interesting to test it with some flux on the board. Thats when the too bright lights getting annoying, because then there are reflexoins everywhere. would be interesting with polarized in comparison.With2 lights,left and right there is no glare at all in this situation.
WOW, that's a great idea! I suffer a lot with the light glare on my setup! I never thought of using a polarized film or lens! Thanks!
Very immpressiv! Thank you Sorin. God bless you!
good find , great video , as a fisherman used many years ago polarized glasses to see where fish was under glare , , and used these on photoraphy cameras I still have such filter and will try, but anyway you is right !!!
The light color yellow is not ideal the first one is still better for me
Links for everything BUT the light! way to go
Good product, I just ordered it based on what I've seen. They don't supply it to Spain, but I order it from Italy, where a brother of mine picks it up and sends it back to me. The work he does is perfect, the reflections of the metal flux and other things that make vision very difficult are very uncomfortable. good job and thanks for the video
Looks great nice tool impressive
Time to do some repair videos!
Finally, pixel count is not important in cameras but pixel quality is. I was producing billboard images and magazine page size product photographs with a 3 megapixel camera. This was with the first digital cameras. Just like with amplifiers, passing a clean signal to the speakers is important to the observer. Listeners do not need not know that it came from an iPhone size amp or a $50,000.00 amp. The observer judges the sound and there are as many opinions as there are people. I could not show my clients the equipment as I was using an Nikon 990 amateur camera. All my lighting was pro quality flash units/studio strobes. I used software in DOS to align the red, green and blue images from the poor tiny camera lens to bring them into perfect alignment. Voila a great quality image! Pixels are to record details. More pixels, more detail but not a better picture. Bigger pixels, better quality picture. However, like you, I was a master with my glue gun! (My Nikon 990 and DOS)
I like this light with just a little bit of reflections, not enough to blow the image but not so dull so you can't see clearly solder joints and pins.
That's nice sharing sir you're the best
Unbelievable difference 😮
Good. Have you tried putting the polarizing filter in front of the light source?
Good day sir, please i would like to know the type of work station you are using for adding amperes to computer board
amazing
Thanks
The 14mp mic sold under brand-name hayhear as complete kits on Amazon is similar to the ones Northridge fix used to sell (older model) although they have some kit variants with the regions, some have the ring lite and the polarized lens in the kit for ~300$ not sure about the components since I got mine mic only, no kit for significantly pricier on Ali 2 yrs ago.
Just try on Ali btw he just taking money for those which do not know to go on web and search...i really liked him before but he advertise him self tooo much and it is boring...always "You can buy from our web shop" omg bro you just want money and then speaking in videos i have no time for kids and family ofc u don't have...just runing for money...also he blocked my comment because im telling the truth and he probably wont accept it...
i have hayear microscope too. it is same features like amscope . no need to spend more money.. i remember i have bought it half price of amscope even cheaper .. ne need to get fool.
Hi, Sorin. Could you kindly provide us with link where to buy this Microscope polarized LED ring light. Thanks a lot!
Nice find Sorin.. thanks for the share..
Angle of incidence = angle of reflection. The angle that a light hits an object is the angle at which it reflect off the object in question. If you shine light on to an object at 90 degrees it is going to reflect back into the camera lense at the same angle. A law pf physics.
Leds are directional, i sand paper leds to produce a diffused/scattered light, handy for replacing bulbs. Polarising filters reduce glare, like polaroid glasses. Sorin, your microscope looks so much better, maybe you sell filters to help block glare.
where do you get it from?
Hello... I think the your idea will be much better if you used the flux on the board to show the cancelation of the glare 😉 God bless you 🙏👍❤️😊
The polariser is blocking the reflected light which itself has been polarised by the light unit. This effectively means you are just not seeing the light you shine onto the board. @7:22 of the video you can see that when you remove your first light you can see the capacitors, etc. very well. A cheaper solution is just turn off the microscope light when it gives too many reflections so you can see the details you need using diffuse ambient light instead. Effectively 'turning down' the light with a polariser is really just wasting the money you spent on the light in the first place. Microscope near a window with a big white reflector on to the work area is best cheap option if you have daylight. Good video though. Love all your fix work.
This is amazing !!!
I Sorin, what brand of câmera do you use?
the microscope camera? Is unbranded from ebay
It is not just a problem with the dynamic range of the camera, it is rather a problem with the ring lights that they sell. I have a fairly quality camera but the light ruins everything because it is a non-polarized ring, you can put the best camera in the world If you don't polarize the light you will have that problem
Thank you, I am going nuts because I just spent $700 on a microscope camera and it sucks....colors are horrible and blurry. I will give this a try next...
You can adjust the contrast, the brightness, the RGB, the gamma and whatever you want, you can improve the situation a little but you will never leave an image as clean as the one you show in your video no matter how much quality the camera has.
That camera/lens has a problem with colour convergence. On the left side of the picture you can see how distorted the colour is.
Un link cu acel ring ?
Polarized light was/is used in the copying of art work in museums. Light aimed at an imperfect surface like an oil painting scatters and causes specular reflections into the lens that are not part of what you are photographing. These reflections that ruin the image can be removed if two light sources are used on the side and both have a polarizer gel in front of it. Both polarizer gels need to be in the exact aligned position shining to the object. With the a linear polarizer on the camera in 90 degree away alignment to the lights the reflections disappear and are zero! Rotating the polarizer on the camera then allows more or less reflections. Due to lack of reflections paintings look often lifeless but that is another topic for another day. Obviously Electronics share a lot of these principles as all wave forms are bound by the same physical laws. Rinus
It seems the same can be achieve by just using a very weak light source
Comparing apples and oranges is the big problem here. Firstly your microscope is set up to look exactly down the middle of your ring light. So that is setting the parameters for any other camera comparison. Remember that when it comes to reflections, angle in is also angle out! That means if the light enters at 45 degrees on a reflecting (like a mirror) surface the light also exits that surface at 45 degrees. The microscope looks straight into the reflected light or does it? It does NOT! The ring light comes from the side and to be precise, all sides around the periphery. The lights enter with a slight angle and then exit with a slight angle opposite of the optical axis of the lens. The optical axis is exactly down the middle and it does misses the reflection Aiming the microscope at a subject/object that scatters the light will reflect it not only as I described but also into the lens. The reflectivity of any shiny object is in photography described as specular reflectivity. It is like the sun reflecting in an apple. That spot is very bright compared to the rest of the apple. In fact if you tried it on a silver (Christmas ball) the dynamic range of any camera no matter how expensive or even our eyes cannot see any detail in both areas at the same time. So specular highlights are neve considered in dynamic range measurements. So to be fair in your video, the capacitors are your specular highlights that are too bright to be seen together with he rest of the board due to the direction/position of the ring light. They scatter light into the lens. Camera phones or digital cameras may be better but the camera is not the problem. If one could remove the microscope camera (but leave the light in place) and replace it with a phone or pro camera and according to the fixed parameters place the lens in the same exact optical axis the capacitors will look the same. You actually did that in your video (for only a second) while aiming your phone over the ring light. Years as a product photographer the lesson was not the camera or the film or digital imager, it was lighting! I am now going to watch another of your videos as I am trouble-shooting a power board in an LG LCD LED TV that only has correct voltage when the main board is connected to it at 13.25v but only has 8.8v when I disconnect it. It never ends. Thanks for your great patience in doing your videos. Rinus, Greets from Canada
you can see right thro- the caps lol , thats annoying to just to see lol by the way what type of camera's are using for your video's?
❤️
It's not the light that does .the magic, it's the polarized filter. So a good pair of sunglasses or camera polarized filter with the old 120 LED lamp would do the same thing. Also if you take an LCD screen apart you can use one of the layers to filter the light.
Wow third video today
That's why fisherman wears polarized glasses to cancel the reflections on the water
I the list of components you use, there is no mention of the microscope you have, I'd really like to know that one or something like it. This is just for myself so not for business
👋👌 thanks
In photography we generally do not use full polarization. We turn it back a bit to get the life back in the picture. In your demo, full polarization is difficult to work with. All depth disappears. We need to see at least a bit to see what we are doing. no shine on solder looks like a good solder joint. A bit of a shine will show the crack in a cold solder contact. Just saying. Rinus
Has anyone found a bigger ring light with a diameter bigger than 70mm
it looks all yellowish makes me queasy , normally I like warm light but not this one , I prefer the bright light in this casy , much clearer and more rich details
proof is in the pudding :)
This is much better than NorthridgeFix's solution for microscope light glare. It replaces the existing microscope ring light and it doesn't take extra space - especially when you have small work desk.
And yet northridge fix solution looks 1000% better than sorins budget myth hack
@@waynetaylor2784 "sorins budget myth hack" lmfao, what is this cope???????
@@AeRiaL_ yeah I'll keep my opinion with 37yrs in the industry and 6 repair shops. I'm pretty sure I and the rest of the professionals out there know the truth. You believe what you wanna believe n waste your money on whatever you want. Doesn't bother me in the slightest
@@waynetaylor2784 I looked up the cost, it's almost the same price. NorthridgeFix use AmScope LED-6W which cost $130 on Amazon - NorthridgeFix branded their own name and sell it for $149. I checked on Aliexpress the cost for this light is $125. So cost wise they are the same. But this is a better solution if you have a smaller work desk
@@danfromtechnesia yeah don't think so your looking at 120 led model not Sorins 16 led model way more expensive
Sharp that cam please :)
You could get a CP filter for $2 and do the same thing.
Link pls
The microscope light really importan and very difficult to buying for properly
Not sold on the idea, aside from being an expensive option - it's all about the angle that actually causes glare. I give Alex @ NRF credit on his non glare solution, best solution for the price.
Well, his solution is using the ring light+the gooseneck light. They cost a total of ~150$ right now on Alie, so it`s not really cheap either. The polarized light from this vid is ~170$ on Alie. Both solutions are good though.
u use polarize to see smd numbers and phones models hahaha
The image is still a garbage. I have the same polarizer (200 euro) from aliexpress and with my eakins IMX307 or IMX385 Sony sensor it's a killer. And when you add also gooseneck 2x3W led light the image is even better. I don't know what kind of sensor is inside your camera but definitely this polarizer is not showing his full performance with your camera.
Couldn't u just put on sunglassss
i like no light

Well gosh, I checked aliexpress today and these things now cost nearly 200 euros... what is that a 500 % increase since this video was done?
